BIOS 1700 chapters 14-19 Questions
and All Correct Answers.
meiosis - Answer parents gametes fuse to make new organism during sexual reproduction
meiosis 1 outcome - Answer 2 unique daughter cells with 2 chromosomes in each, one big
and one small
meiosis 1 prophase - Answer long and short homologs from each parent find match
synapsis - Answer in prophase 1, chromosomes crossover and exchange pieces
chiasma - Answer chromosomes crossing over
meiosis 1 anaphase - Answer chromosomes are pulled over but chromatids stay together
meiosis 1 telophase - Answer two cells are formed with half the amount of chromosomes
but same amount of DNA
meiosis 2 outcome - Answer 4 unique daughter cells with 2 different chromatids in each, one
big and one small
meiosis 2 outcome in males - Answer 4 sperm
meiosis 2 outcome in females - Answer 1 enlarged oocyte, 3 polar bodies that get eliminated
nondisjunction - Answer failure of chromosomes to separate properly
mitochondrial DNA - Answer specific DNA made inside mitochondria
# of genes encoded in mitochondria - Answer 14
what process are mitochondrial genes used for - Answer oxidative phosphorylation
mitochondrial abnormalities are transmitted by... - Answer females only but passed down to
all offspring
, mendel's experiments - Answer used inbred breeding to follow traits of pea plants
reciprocal crosses - Answer reverse male and female roles to see if sex contributes to
characteristic
allosteric regulation - Answer controlling enzyme activity
presence of enzyme activity is... - Answer dominant
principle of segregation - Answer 2 alleles in each parent, offspring receives 1 of each
testcross - Answer determining genotype by crossing with homozygous recessive
incomplete dominance - Answer two phenotypes are partly expresses
codominance - Answer two phenotypes are fully expressed
independent assortment - Answer 2 traits do not affect each other
linkage - Answer 2 traits that are linked to each other are always on the same chromosome
incomplete penetrance - Answer receiving 1 mutant allele that increases your risk of a
certain disease/mutation
complex traits - Answer multiple genes work together to make one trait
complex traits are always... - Answer quantitative and continuous
environmental risk factor - Answer environment affecting phenotype
hertiability - Answer variation in a population on a scale of 0-100%
identical twins - Answer 1 fertilized oocyte splits, shares all the same DNA
